ghc-6.4.1: panic - Prelude.last: empty list

[Einar Karttunen]

Hello

I am having problems with GHC 6.4.1 dying with the message:

ghc-6.4.1: panic! (the `impossible' happened, GHC version 6.4.1):
        Prelude.last: empty list

The source is nontrivial and contains template haskell. The error
seems to appear after byte code generation.

The log of the compile with -v9 is at the address below:

Is there anything else I should do to isolate the error better?
